Y MINE-RAILWAY.

(.SPECIFICATION forming part; of Letters Patent No. 314,010, dated March17, 1885.

. Application filed January 14,1855. (No model.)

To aZZ whom it may concern.-

Be it known that we, JOHN C. FowLE, JOHN P. CHRISTOPHER, and WILL P.SMITH, all of Michigamme, in the county of Marquette and State ofMichigan, have invented a new and Improved Mine-Railway, of which thefollowing is a full, clear, and exact description.

The object of our invention is to lessen the cost of transportation ofore, coal, &c., by utilizing part of the power of the hoistingrope foroperating a surface-car.

The invention consists in a winding-drum and gearing suitable foroperating it from a pulley over which the hoisting-rope passes, the ropefor operating the surface-car being connected with the said drum.

Referenceis to be had to the accompanying drawings,forming part of thisspecification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a longitudinal sectional elevation of a shaft-house and partof the mine, showing the arrangement of our improved mine-railway. Fig.2 is an enlarged side view of part of the gearing.

The shaft A is journaled in the shaft-house B, and on it is mounted agrooved pulley, C, over which the hoisting-cable D is passed, whichpasses from the engine-house and extends down the inclined shaft E andis secured to the skip F, running on tracks G in the shaft E, and on thetracks G, extending upward from the shaft, and provided with a dump, H,near its upper end, at which the skip F is dumped automatically.

An inclined track, J, leads from the shafthouse to a dumpinggrouud, orto cars, vesscls, 850., or wherever the ore, coal, &c., are to bedeposited. On the track J the (lumping-car K runs, which is secured to acable, L, passed over an angle-pulley, I, and secured to and wound on adrum, M, journaled on a frame, T, having one end pivoted at N, andhaving the other end connected with a lever, O, pivoted in suitablehangers and provided with a pulling-rod, P.

A grooved friction-pinion, Q, is formed on the shaft of the drum M, oron one end of the drum, and is adapted to be engaged wit-h afriction-wheel, R, rigidly mounted on the shaft A.

The operation is as follows: The skip F is pulled upward in the shaft Eby the cable D,

and thereby the pulley G is revolved, over which the cable D passes. Therod P is pulled down, whereby the frame T is raised, and thefriction-pinion Qis brought in contact with the wheel R, and the drum Mis revolved from the wheel R, the rope Lis wound on the drum M, and thecar K is moved in the direction of the arrow at, and by the time thedumping-car K is under the dump H the skip F arrives at the dump anddumps its load into the car K. The rod P is released, the frame T movesdownward slightly, and the pinion Qand wheel R are disengaged, thuspermitting the car K to run down the inclined track J and the cable L tounwind from the drum M. In the meantime the skip F is lowered, and whenit is again raised the pinion Q and the wheel R are engaged and the carK is pulled in the direction of the arrow a again.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a pulley over which a hoisting-rope is to bepassed, of a drum, gearing for revolving the drum from the said pulley,and of a cable or rope secured on the said drum and connected with adumping-car, said cable being passed over the an gle-pnlley,substantially as herein shown and described.

2. The combination, with the pulley C, over which the hoisting-cable Dis to be passed, of the wheel R on the same shaft with the pulley O, thepivoted frame T, the drum M, journaledin the same. the pinion Q,connected with the drum, the rope L, secured on the drum, and thedumping-car K, secured to the said rope L, substantially as herein shownand described.

3. The combination, with the shaft A, of 9 the pulley O and thefriction-wheel R on the same, the pivoted frame '1, the lever O, thedrum M, and the pinion Q on the frame T, the rope L, the track J, thecar K, the track G, and the dump H, substantially as herein I shown anddescribed.
